Operation
Set-Up Procedure
Multi-Signal Module
Two additional levels of "advanced" set-up
features are available. The first level is
used to adjust basic communication
related parameters. The second level is
used to adjust alarm repeat time and
display intensity.
Setting Communication Parameters:
A network address uniquely identifies
each multi-signal alarm module to a
personal computer or Johnson Controls
Metasys® system. Address range is 0 to
255. Factory default setting is 0. Since a
multi-signal alarm module does not have
a digital display, network address is
shown as a binary number on specific red
and green front panel LED indicators.
Table below assigns a numeric value to
each specific LED indicators. For
example, if LED indicators for bits 0, 1, 2,
and 3 were all illuminated, network
address would be 15 (1+2+4+8=15).

1. Press and HOLD set-up button.
Audible alarm will chirp when set-up
button is first pushed and again two
seconds later. Release button after
second audible alarm chirp. Multi-
signal alarm module front panel LED
indicators (Bit 0 through Bit 7) will
show current network address. If no
indicators are illuminated, address is 0
(factory setting).
2. Using either
desired network address between 0
and 255.
3. Press and release TEST button on
front of alarm panel. Front panel LED
indicators (Bit 0 and Bit 4) will show
current communication baud rate. If
only Bit 4 LED is illuminated, baud
rate is 4800 (factory setting). If BOTH
Bit 0 and Bit 4 LEDs are illuminated,
baud rate is 9600.
4. Using either
desired baud rate (4800 or 9600).
5 Press and release TEST button on
front of alarm panel. Front panel LED
indicators (Bit 1 and Bit 5) will show
current communication data format. If
only Bit 5 LED is illuminated, data
format is 8-bit word length (factory
setting). If BOTH Bit 1 and Bit 5 LEDs
are illuminated, data format is 16-bit
word length.

6. Using either
desired data format (8-bit or 16-bit).
7. Press and release TEST button to
